The answer to this question is dependant upon a number of factors some specific to your company's health insurance scheme and some specific to the medical condition. Group health insurance policies can be underwritten in one of three ways; full medical underwriting, moratorium and medical history disregarded.
Regardless of the policy underwriting the general everyday treatment of chronic conditions tends not to be covered, private medical insurance is designed to provide you with access to private healthcare for the treatment of acute conditions.
With a fully medically underwritten scheme you would disclose your past medical history when joining the scheme and the insurer will make a judgement based on the information disclosed as to whether any exclusions are to be added to your plan.
A plan underwritten on a moratorium basis usually states that any medical conditions suffered in the past 5 years will not be covered for the first two years of the policy. Should you not suffer any symptoms of that condition during the first two years of the plan it will be reincluded within the policy.
If your company scheme is large enough the policy will often be underwritten on a medical history disregarded basis. With a medical history disregarded plan there is no need to declare your medical history and acute pre-existing medical conditions will covered upon joining the scheme.
